Let's start with CalAmp, which disconnected with Wall Street after a disappointing quarter. The provider of wireless and satellite solutions clocked in with an adjusted profit of $0.20 a share, just short of Wall Street estimates. Revenue climbed 24% to $59.8 million, but that, too, couldn't match the $61.5 million the pros were projecting. CalAmp's guidance for the current period also didn't keep up with where analysts were perched.

Organovo continued its slide. The upstart bio-printing company, which has the ambitious goal of creating a proxy for human tissue in a lab that could be used to speed up drug testing and other procedures, was on a roll last year when 3-D printing was in fashion. This year has been a lot harder on the niche, and Organovo has now seen its stock shed 59% of its value since peaking in November.

Yandex stumbled on fears that Russia will be tightening its online restrictions. Russian stocks were already weak in recent weeks as military maneuvers in the region spooked investors. This past week we saw Vladimir Putin mention the leading search engine, when he suggested that the Western influence on Yandex could be problematic. Yandex countered with a press release pointing out how many start-ups have international investors as members of their governing bodies. That wasn't enough to keep the stock from hitting a new 52-week low.

Finally we have ServiceNow taking a hit despite posting better-than-expected financial results. The provider of IT infrastructure solutions saw its revenue climb 62% to $139.1 million, while the market was settling for just $134.6 million on the top line. Revenue guidance for the current quarter was also ahead of analyst targets. However, when the market's showing signs of vulnerability -- and that's just what happened when the Nasdaq tumbled later in the week -- it's going to take down some of the newer names that have yet to find their ways to profitability.
